I have an rv42 router. I want to have two separate networks. One for the office, another for the guests via additonal wifi router. Is it possible to set up the router with the following: The office computer connects to the 4 lan ports of the router. The guest computers are connected via additiona wi-fi router, that is connected to the dmz/internet port of the router. How to set it up? Both networks should acces the internet, but shouldnt see any resource of the other network.
